Krumschnabel G, Wieser W (1994) Experientia
Abstract: In isolated goldfish hepatocytes underaerobic conditions the energy requirement for the sodium pump (calculated from Rb+ flux) is closely matched by the ouabain-sensitive fraction of oxygen consumption, whereas during in vitroanoxia (cyanide inhibition of the electron transport chain) the measured ATP demand of the sodium pump clearly exceeds ouabain-sensitive ATP production by anaerobic glycolysis. We conclude that when the energy status of cells is low, part or all of the ATP spared by the inhibition of a particular function may be used for fuelling other ATP-consuming functions. β’ Keywords: goldfish, hepatocyte, sodium pump, protein synthesis, membrane-metabolic coupling, lactate, ouabain
